django - 在 OAuth2.0 dance 中找不到服务 "memcache"的 api 代理

Question

我尝试在我的应用程序中实现 OAuth2.0，但遇到了问题，但现在无法修复。

错误是:

Traceback:
File "/home/i159/Envs/photorulez/lib/python2.6/site- packages/django/core/handlers/base.py" in get_response
111.                         response = callback(request, *callback_args,   **callback_kwargs)

301.     assert stub, 'No api proxy found for service "%s"' % service

Exception Type: AssertionError at /get_access_token/
Exception Value: No api proxy found for service "memcache"

代码是:

CONSUMER_KEY = 'anonymous'
CONSUMER_SECRET = 'anonymous'
SCOPES = ['https://picasaweb.google.com/data/',]

def oauth2_login(request):
    client = gdata.docs.client.DocsClient(source='photorulez')

    oauth_callback_url = 'http://%s/get_access_token' % '127.0.0.1:8000'

    request_token = client.GetOAuthToken(
        SCOPES, 
        oauth_callback_url, 
        CONSUMER_KEY, 
        consumer_secret=CONSUMER_SECRET)

    request.session['request_token'] = request_token
    return HttpResponseRedirect(request_token.generate_authorization_url())


def get_token(request):
    client = gdata.docs.client.DocsClient(source='photorulez')
    saved_token = gdata.gauth.AeLoad(request.GET.get('oauth_token'))
    uri = 'http://127.0.0.1:8000'

    request_token = gdata.gauth.AuthorizeRequestToken(
        saved_token, 
        uri)    
    access_token = client.GetAccessToken(request_token)

    client.auth_token = gdata.gauth.OAuthHmacToken(CONSUMER_KEY,
        CONSUMER_SECRET,
        access_token.token,
        access_token.token_secret,
        gdata.gauth.ACCESS_TOKEN)
    return HttpResponseRedirect('/')

我刚刚通过 pip 安装了 google_appengine-1.5.1 模块，我的应用程序在 Django 开发服务器上运行。我能做什么来修复它？我应该只在 GAE 上运行它吗？

看来您需要运行 GAE，因为 OAth 实现使用 GAE 内存缓存服务。您告诉 GAE API 您的 Django 服务器将处理 GAE 调用。您可能需要运行 GAE 开发服务器，以便它可以处理请求。

如果您不想运行 GAE 服务器，则看起来像 this blog entry显示了运行足够的 GAE 来服务此请求的代码。
